WitrynaImmersion silver or ENIG. I've been designing circuit boards professionally now for just over 3 years. The field is defense. For reasons that have been been quite made clear to me all the boards I've worked on have been immersion silver finished. This send to have favorable properties for high RF and does a decent job maintaining solder ability. WitrynaIm-Ag is a short form of immersion silver that aims to generate a silver layer due to the effect of solution. Instead of a pure silver layer, Im-Ag contains organic substance whose mass fraction is approximately 30%. • Disadvantage Discussion. a. Micro Cavity Micro cavities whose diameter is less than 0.05mm tend to be caused on silver surface.
